How to Create an API Texting Service using Twilio SMS and Python

Twilio provides a simple interface for sending SMS text messages through their SMS API. A Python and FastAPI framework is used to create an API texting service that can be tested using Pytest and deployed to Heroku using Docker. The application sends SMS messages using the Twilio SMS API, handles edge cases, and returns JSON responses. After deployment, the application can be accessed through a Swagger documentation interface.
